Definitions

  • the present invention relates to low foaming surface active agents. More particularly, the invention aims to provide novel low foaming surface active agents having enhanced biodegradability as well as improved performance as rinse aids in automatic dish washing and hard surface cleaner applications.
  • Biodegradability is defined as that property possessed by a material enabling it to be decomposed by bacteria or other living organisms.
  • surfactants utilized in the washing of tableware in automatic dishwashers will have a combination of biodegradablity characteristics and improved rinsing properties.
  • U. S Patent No. 3,956,401 discloses liquid surfactants having the formula: wherein R is a substantially linear hydrocarbon and more particularly an alkyl group having an average of from about 7 to about 10 carbon atoms; R' is a linear, alkyl hydrocarbon of from about 1 to about 4 carbon atoms; R" is a linear, alkyl hydrocarbon of from about 1 to about 4 carbon atoms; x is an integer of about 1 to about 6; y is an integer of about 4 to about 15; and z is an integer of about 4 to 25.

  • x is an integer having a value from about 6 to about 40
  • y is an integer having a value from about 8 to about 50.
  • the ratio of x:y is from about 2:8 to about 8:2; and the mole ratio of dicarboxylic acid to epoxy-capped poly(oxylalkylated) alcohol is from about 1:1 to about 10:1.
  • the above-described surfactants typically have high caustic solubility, which can be an important surfactant characteristic.
  • an increased emphasis on biodegradability and surfactant cleaning performance in the cleaning of tableware, particularly when utilizing detergent compositions having low phosphate concentrations has resulted in requirements which are not completely satisfied utilizing the compositions described in the above referenced patents.
  • New nonionic surfactants have been discovered which have surprisingly improved rinsing characteristics, are readily biodegradable, and are low foaming. Their use results in a significant reduction in spotting and filming of tableware, as compared to conventional surfactants, when used in automatic dishwashers.
  • the invention provides an epoxy-capped poly(oxyalkylated) alcohol characterized by the formula: R 1 O[CH 2 CH(CH 3 )O] x (CH 2 CH 2 O) y [CH 2 CH(OH)R 2 ] wherein R 1 is a linear, aliphatic hydrocarbon radical having from 4 to 18 carbon atoms or a mixture of linear, aliphatic hydrocarbon radicals having an average of from 4 to 18 carbon atoms; and R 2 is a linear, aliphatic hydrocarbon radical having from 2 to 26 carbon atoms or a mixture of linear, aliphatic hydrocarbon radicals having an average of from 2 to 26 carbon atoms; x is an integer having a value from 1 to 3; y is an integer having a value from 5 to 30, the ratio of x:y being between about 1:5 and about 1:30.
  • Preferred surfactant compositions include those in which x is an integer having a value from about 1 to about 2, and more preferably 1. Also preferred are surfactant compositions in which y is an integer having a value from about 10 to about 25, and more preferably from about 10 to about 20.
  • the present invention provides an automatic dishwasher composition comprising the above-described epoxy-capped poly(oxyalkylated) alcohol and at least one component selected from detergent builder, bleach, anti-wear agent, and mixtures thereof.
  • the present invention provides a cleaning composition for cleaning hard surfaces comprising an aqueous or organic solvent and the above-described epoxy-capped poly(oxyalkylated) alcohol as a surfactant.
  • the FIGURE is a graph showing the rinse efficacy of the products of the invention, EXAMPLES 1, 2 and 3, and COMPARATIVE EXAMPLES C and D with respect to spotting of washed glassware.
  • the surfactants of the present invention consist of four components, namely a linear alcohol, propylene oxide, ethylene oxide, and an epoxy cap.
  • the epoxy cap and the linear alcohol serve as a hydrophobic, oil-soluble portion of the molecule.
  • the ethylene oxide groups form the hydrophilic, water-soluble elements of the molecule.
  • compositions of the present invention to clean tableware.
  • the present inventors believe that this improvement is at least partly attributable to the ordered structure of the compositions in which limited numbers of propylene oxide groups are directly attached to the alcohol followed by addition of the ethylene oxide groups and capping using the 1,2-epoxyalkane. While maintaining this ordered structure, it is desired to also have low ratios of propylene oxide groups to ethylene oxide groups. For example, preferred ratios of propylene oxide groups to ethylene oxide groups are in the range of about 1:5 to about 1:30, and more preferably from about 1:10 to about 1:20.
  • these poly(oxyalkylated) alcohols may be made by condensing an aliphatic alcohol, or mixture of alcohols, having an average chain length of from 4 to about 18 carbon atoms, preferably from about 4 to about 12, and more preferably from about 6 to about 10 carbon atoms, initially with propylene oxide followed by capping this condensation product with ethylene oxide.
  • the methods used for condensing and capping may be any of the well-known methods described in the art.
  • these reactions occur at elevated temperatures in the range of about 120°C to about 180°C, and more preferably at from about 140°C - 160°C. It is also preferred to carry out such reactions in the presence of an effective amount (e.g.
  • alkaline catalyst(s) such as hydroxides of alkali metals or alkaline earth metals as well as alkali metal alcoholates and BF 3 .
  • the preferred catalyst is KOH.
  • Epoxy compounds useful for making the epoxy-capped poly(oxyalkylated) alcohols of the present invention include any 1,2-epoxyalkanes, or mixtures thereof, having a hydrocarbon chain containing an average of about 2 to about 26 carbon atoms.
  • the 1,2-epoxyalkane has a linear, aliphatic hydrocarbon chain containing an average of from about 8 to about 20 carbon atoms, and more preferably an average of from about 10 to about 16 carbon atoms.
  • 2 to 4 carbons is preferred if a high cloud point composition is desired, 6 to 10 carbons is preferred to optimize defoaming efficacy, and 12 to 22 carbons is desired to optimize rinsing efficacy.
  • Various 1,2-epoxyalkane compounds are commercially available from Atochem North America Inc., Philadelphia, PA under the product names VIKALOX 11-14, VIKALOX 12, VIKALOX 16 and others.
  • novel surfactant compositions of the present invention provide improved surface treatment of the tableware by the rinse water and subsequently reduces spotting and filming.
  • These epoxy-capped poly(oxyalkylated) alcohols can be formulated in powder and liquid detergent products for automatic dishwashers or in hard surface cleaning products, such as bathroom tile cleaners using methods commercially practised in the detergent industry.
  • These formulations can include, for example, detergent builders, chelating agents, bleaches, anti-wear agents, and combinations thereof, among others.
  • Suitable detergent builders include inorganic builders such as sodium tripolyphosphate (STPP), sodium carbonate, zeolites and mixtures thereof. Where STPP is the detergent builder, the STPP may be employed in the compositions in a range of about 8 to 35 wt. %, preferably about 20 to 30 wt %, and should preferably be free of heavy metal which tends to decompose or inactivate the preferred sodium hypochlorite and other chlorine bleach compounds.
  • the STPP may be anhydrous or hydrated, including the stable hexahydrate with a degree of hydration of 6 corresponding to about 18% by weight of water or more.
  • Organic builders can also be used including nitrilotriacetic acid and alkali metal salts of tartaric or citric acid.
  • a chelating agent can be any one of a wide range of organic or inorganic sequestering agents, examples including phosphoric acid, amino polycarboxylic acids such as EDTA, NTA and DETPA, and polycarboxylic acids such as lactic acid, citric acid, tartaric acid, gluconic acid, glucoheptonic acid, mucic acid, galactonic acid, saccharic acid, fumaric acid, succinic acid, glutaric acid, adipic acid and their alkali metal or ammonium salts.
  • Citric or tartaric acid are preferred chelating acids.
  • the chelating agent if included is present in an amount of up to about 30% and normally lies in the range from about 5% to about 20% by weight. Highly preferred compositions use from about 5% to about 10% by weight of chelating agent in order to minimize any attack by the chelating agent on the glass.
  • the bleach may be an organic chlorine containing bleach, for example, trichloroisocyanuric acid, dichloroisocyanuric acid or a salt of dichloroisocyanuric acid.
  • a sodium or potassium salt such as trichloroisocyanuric acid is employed in an amount of, for example, 1 to 5% and more preferably 2 to 3% by weight in the cleaning composition.
  • Inorganic bleaching compounds such as chlorinated trisodium polyphosphate (TSPP) or lithium hypochlorite may also be used.
